Hydor Slim Skim Nano Skimmer - NOISY

[marxman]

Hi All,

I realize that this is going to be a very subjective post, but wanted to see other's opinions on this skimmer.

I purchased the Hydor Slim Skim Nano for my Waterbox AIO 30.2.
It fits great in the back sump chamber and was quite easy to assemble.

The issue I am having is that my unit seems to be extremely noisy. There is a very noticeable low frequency vibration / hum that I can hear in other rooms in my house.
It has only been running a day or two, but it is so noisy that I am considering running it only a few hours a day.

What have other people experienced with this skimmer?
Do you find it noisy?
Does it quieten down once it "breaks in".... not sure if this is even a thing

They are very quiet skimmers, check the impeller to see if it is damaged in any way. Also check if there is any excessive bubbles going into it.

Thanks for the note.
I have taken the skimmer apart and have noticed that the impeller seems to be making the loud hum and rattling noise. Not really sure how to quieten it, but will try a few things

Is the impeller separated? Pic?

the green impeller piece, the magnet, and the little green washer on the bottom were all separate... if thats what you mean.

I did try applying a spot of glue to keep the magnet on the sleeve and the little washer on the end of the magnet.

When i reassembled the impeller / cage / motor it still makes the rattling noise... so not sure if the impeller assembly is moving around too freely

Thats very kind of you Bob.

Do you think there is anything that I can try before replacing the impeller?
I'm assuming I am not missing some piece, certainly doesnt look that way according to the documentation.

No, I think it is the impeller

Im having the exact same problem. How did you get in contact with hydro? Everytime I try to email them I get an error message on their website. I've tried multiple devices.

It is Hydor, not Hydro and the email is [email protected]

My skimmer is making a rattling noise now which it has never done. How do I open the motor portion to check the impeller and to clean it? Do I pull or twist the pieces off?

The email for Hydor shown above comes back as undeliverable.

The manual has good enough pictures to see how it comes apart.

I had already downloaded the instructions and can’t make sense if the top piece pulls or twist off. I’ve tried both with great force, afraid I’m going to break something. Hope that someone who has one or who has taken if apart can answer. Thank you.

Solved: All parts snap straight off, no twisting.
